In addition to the iron frigate Achilles, 50, 6,079 tons, 1,250-horse power, building at Chatham dockyard, the following squadron of iron vessels are now under construction by private firms for the Admiralty, several of which are in a very advanced state - viz., the Agincourt, 50, 6,621 tons, 1,250-horse power, building at Birkenhead; the Northumberland, 50, 6,621 tons, 1,250-horse power, and the Valiant, 32, 4,063 tons, 800-horse power, building at Millwall; the Minotaur, 50, 6,621 tons, 1,250-horse power, and the Orontes, 3, 2,812 tons, 500-horse power, building at Blackwall; and the Hector, 32, 4,063 tons, 800-horse power, building at Glasgow. The following iron-plated frigates are now building at the several Royal dockyards, the whole of which are intended to be afloat during the present year - viz., the Caledonia, 50, 4,045 tons, 800-horse power, at Woolwich; the Ocean, 50, 4,045 tons, 1,000-horse power, at Devonport; the Prince Consort, 50, 4,045 tons, 1,000-horse power, at Pembroke; the Royal Oak, 50, 3,716 tons, 1,000-horse power, at Chatham; and the Royal Alfred, 50, 3,716 tons, 800-horse power, at Portsmouth. in addition to the above there are no fewer than 31 line-of-battle ships and other screw steamers now on the stocks at the several dockyards, most of which are admirably adapted for conversion into shield ships, on Captain Coles's principle. Of these the Bulwark, 91 , at Chatham; the Repulse, 91, at Woolwich; the Robust, 91 , at Devonport; and the Zealous, 91, at Pembroke, are all in a very advanced state, requiring only a comparatively small outlay to plate them with iron. There are also three first-class 51-gun figates also building - viz., the Belvidera at Chatham, the Tweed at Pembroke, and the Dryad at Portsmouth, - which are admirably adapted for conversion into armour-plated ships. They would not require the removal of any decks, as would be the case with line-of-battle ships, but would only have to be lengthened and strengthened to enable them to bear the increased weight which would be placed on them. Of the other vessels in progress several are intended to carry 22 guns and upwards. If completed as iron-cased steamers they would be larger and of greater tonnage than either the Monitor or Merrimac. The whole of the hands have been removed from the wooden ships building at the several dockyards, and are now employed on the iron-cased frigates under construction, five of which will be afloat by the end of the present year.
